Central Arizona DX Association


April Meeting

We are the largest ham radio DX club in Arizona with over 130 members, many of whom are on the ARRL's DXCC Honor Roll.  We have several members who have traveled to distant places to put "rare" countries on the air.  We encourage any ham interested in DXing to join our club and learn about the many aspects of talking to hams around the globe who share this amazing hobby with us.  Founded in 1974, we are an ARRL-affiliated club and a member club of the Amateur Radio Council of Arizona (ARCA).

The April Meeting will be held on Thursday night, April 5th, at the PERA Club.  Our program will be “I’m from the Government Planning Department, and I’m here too”, presented by Dr. Jonathan L. Kramer, W6JLK.   Dr. Kramer is an attorney and heads Telecom Law Firm P.C. in Los Angeles and La Jolla.  For more than 25 years, Jonathan has served over 1,000 private and government clients, including governments in Arizona, as a wireless technology planning advisor and project reviewer. Those projects have also included ham radio tower permitting projects.   

Please feel free to arrive early to socialize with your friends.  Refreshments will be served at the break.  Guests are always welcome.

Our program was presented by Ned, AA7A, about his achievement of joining the "3,000 Club" in the DXCC Challenge.  He is the only ham in W6/W7 to have reached that stellar number.

Ned recounted some of his history from 55 years in the hobby and how he first got the bug to chase DX, how he (temporarily) gave up on 160 meters after reaching 100 countries, and how he realized a few years too late that 30 meters would start counting for DXCC Challenge credit.

His statistics showed that while the chase for new band countries has some correlation with the sunspot cycle, continuing persistence regardless of the cycle was critical to his achievement.

March Meeting Recap

Who needs sunspots?  We have an amazing amount of DX activity in March with DXpeditions to Spratley Is. (9M0W), Kosovo (Z60A), XR0YD (Easter Is.), Benin (TY7C), Congo (TN5R), Rotuma Is. (3D2EU), Equatorial Guinea (3C3W), and Annobon Is. (3C0W).  I hope you are taking advantage of this opportunity to work new ones on multiple bands and modes.  I was able to add several of them on 160m and 80m for new DXCC Challenge credits.  So, we could not work them on 10 or 12 meters --  we could still work them.

A number of us were able to participate with AA7A in the beta testing of the latest FT8 version of WSJT-X for DXpeditions using a sophisticated "Fox" and "Hound" arrangement.  Ned was able to sustain a rate of over 400 Qs/hour for part of that test -- exactly what the K1JT team of developers was hoping to see.  There will be further refinements to the software before it is rolled out for regular use by DXpeditions later this year.  Are the remaining days of RTTY numbered??? Time will tell.

A really exciting development this past month has been the club's adoption of the Slack chat room program for DX spotting.  After several years of frustration with time delays and other issues with our Yahoo Group, this instantaneous means of communication seems to be a worthy alternative.  As I write this, we have 54 members on the Slack channels.  Send me an email if you want to join us there.  The Board will consider the future of the CADXA Yahoo Group at its next meeting.  Many of the large reflectors have recently moved from Yahoo to and we will consider that option.

At the March CADXA Board Meeting there was approval of two nominations for the CQ Magazine Halls of Fame, announced each year at the Dayton Hamvention.  We nominated Ned Stearns, AA7A, for the DX Hall of Fame and Fred Lloyd, AA7BQ, President and Founder of, for the Amateur Radio Hall of Fame.  I will let you know what happens with those nominations.

I hope to see some of you at the International DX Convention in Visalia, April 20-22.
